To all whom. it may concern:

Be it known that l, HENRY Melanin, a citizen of the United Stat-cs. residing at Oakland, in the county of Alameda and State of California, have invented certain. new and useful Improvements in Windowficreen Hinges, of which the following is a specification.

My inventlon 1s an improved window screen. hinge including a pair of interchangeable detachable leaves which may be used on either side of the screen.

Referring to the annexed drawing in which my invention isillustrated and which. forms a part of this specification:

Figure l a front view of a screen window with the screen hinged by my hinge to the window frame.

ltigzure 2 is a vertical section of the win dow fran'ie taken on line 2--2 of Figure l.

Figure 3 is a plan view of one of the hingeleaves.

My hinge includes two leaves '1.-l, which are identical in construction. Each leaf has a hook 2 at one corner, an offset 3 diagonally opposite said hook, a vertical. slot l in said offset, a vertical slot 5 about midway between the slot 4; and the hook side of the leaf. and a screw hole 6 below the slot 5.

it leaf 1 is scciired tolthe inside of each. side member of. the window frame 7 imme diately under the upper frame member. with its hook 2 uppermost and projecting outwardlv and upwardly from the frame. iiaid [leaves are secured 1n position by screws 8 and 9 driven respectively through the slots 5 and the holes 6 in said leaves into the side frame members.

A leaf 1 is secured to the front of the frame of the window screen. 10 at each upper .llaid leaves are secured in position on the screen by screws 11 and 12 driven through the slots 5 and holes 6 in said leaves.

In placing the. screen in position in the window frame the hooks 2 of the leaves se cured to the window frame are inserted through the slots f in the leaves secured to the screen, whereby the screen is hung in the frame so that it may be swung open or closed from its upper edge, the hooks 2 of the leaves secured to the window frame and the slots l of the leaves secured to the screen, forming the fulcrums of the screen hinges.

in securing the hinge leaves in position the screws 8 and 11 are first driven through the slots 5 into the screen and frame and the leaves adjusted so that the hooks 2 of the leaves secured to the window frame register properly with the slots 4: of the leaves secured t the screen. The screws 9 and 12 are then driven through the holes 6 into the frame and screen.

The screen may be removed from the frame by swinging it up into horizontal position and disengaging the slots at of the screen leaves from the hooks 2 of the frame leaves.

Having described my invention, l. claim:

A hinge including a pair of leaves. a hook. extending from one corner of each leaf, an offset on each leaf. diagonally opposite the hook of the leaf, the offset of each leaf having a slot to receive the hook from the other leaf and Ineansfor securing the leaves in position.

In testimony whereof I my signature.
